By the next morning everyone was gone . It was alright 9am when Isamu woke up. He groggily went to take his breakfast then prepare himself for school. Luckily Sona had already cooked for him but her instructions were quite discouraging .
" Get late to school and I will personally punish you " Was the note written on the breakfast. Isamu discarded it not because he saw the threat as an empty promise but as a weak one.
After finishing everything he walked to school but was intercepted by Issei in the middle.
" Why aren't you in school ?" Isamu asked.
Issei gave out a fake face full of worry.
" I was worried about you . Perhaps your girlfriend had done something to you " Issei said mustering the best worried face.
Isamu however scoffed.
" Yeah right , you of all people are worried about me " Isamu said.
" But it is the truth . Sona isn't exactly human . She is a devil and they are horrible creatures that feed on people " Issei lied. Isamu had to commend his acting skills but he had eons of experience plus knowledge about Sona.
" Kind of like you right ?" Isamu asked shocking Issei but he still acted like he didn't know .
" What do you mean ? "
" Cut the crap . Sona told me everything "
Issei's face slowly turned to that of malice.
" Then you should know what I can do to you . Stay away from Sona or Rias or I will kill you " Issei said threateningly.
Isamu just chuckled at the threat making Issei angrier .
" Akeno and Sona will be mad at you " Isamu said.
" Why would Akeno be angry , what did you do to her " He growled.
" Oh , and here I thought you became smart. Can't you see the family resemblance ?" Isamu asked making Issei pause . He noticed the similarities but he couldn't believe it.
" Last time I checked Akeno wasn't half black . "
" Don't you know a thing known as half siblings " Isamu asked . Issei was a plain idiot in all honest.
" Tch , I don't care just do not talk to them , they are mine okay . " Issei said angrily.
" Who is yours " A familiar voice was heard behind Issei . They both looked at the source of voice to see a frowning Sona .
" Oh hi "
" You're both late. I would like to punish the both of you here right now but it seems that Issei has been called by Rias so you will be receive it later. " Issei nodded before walking away. He had no shame in what he had said as he was dumb so his behaviour remained the same.
" I am coming Buchou . "One could here him say from a distance
Sona now turned to Isamu with that same frown.
" You on the other hand will not ... " She was interrupted with a kiss on her lips , her first real kiss. Isamu sensed she was an amateur but he didn't mind. What he currently aimed for was to make her embarrassed .
Sona pushed Isamu away after some while with a deep blush.
" W-what was that ?" Sona asked .
" My punishment " Isamu said.
" N-no that wasn't your punishment . Your punishment was supposed to be ....."
Isamu assaulted her again . Sona at first rejected the kiss but slowly dissolved into it . She enjoyed the kiss until an old man passing through them rebuked them.
" Kids this days, they have no dignity " He whizzed .
Sona blushed madly as she exited the kiss while Isamu maintianed that charming smile.
" Sorry Kuro " He said.
" Ah Juzo's kid , I didn't know it was you ..... So you finally got a girl eh " The old man approached Isamu and started teasing him.
Sona was surprised by the quick change in personality. At first he was disgusted with them and now he was treating them like old time friends ?
" Haha Yes . Old man Juzo would be teasing me everyday " Isamu said.
" Of course he would . Now Don't stand there introduce me to the beauty. " Kuro said.
" Ah yes , this is Souna Shitori , my future wife " Sona extended her arm to greet Kuro but midway blushed heavily at what Isamu said.
" A pleasure to meet Miss Shitori , kindly treat my best friends grandson well and if you don't ... " Kuro released an ominous aura that surprised Souna .
" Ah but I know you will . And please don't do those indecent acts in the open " Kuro said he then released her hand and walked away.
The two decided to walk back to school .
" .... Did you feel that killing intent ?" Sona asked after some while .
" Yeah old man Kuro was a military personnel that fought in world war 2 and not those normal soldiers , he was a straight up psychopath who killed hundreds probably even thousands of people so his killing intent isn't that surprising "
" Are you scared " Isamu teased .
" Tch of course not . I am a devil , what could a mere human do to me " Sona proudly declared.
" Riighht ~ "
" You don't believe me " Sona asked angrily . They now passed through the school gate .Sona had already forgotten the punishment she had set for Isamu due to those two kisses just as Isamu had intended .
" Of course I believe you , I just find you cute " Isamu said. Sona just turned her head sideways.
" Smooth talker " She murmured under her breath but Isamu obviously heard it .
As they went to the school building , suddenly a powerful aura appeared on the ORC .
" What's happening ?" Isamu asked.
" That aura , it's my sister's " Sona said in slight fear.
" Cool , I get to meet your family . " Isamu said.
" Not cool , she is the type to try and... "
Suddenly a magical girl appeared in front of them .
She seemed enraged .
" Fallen angel what have you done to my sweet So-tan ?" She said.
Isamu sensed her powers. She was at the Profound Immortal realm .
" Sis please stop being annoying " Sona said.
" This beauty is your sister ? " Isamu looked at Sona's boobs then at Serafall .
" I need to raise this issue to the producers "
BANG !!
Isamu received a blow to the head,
" You have already set sights on my sister you pervert "
" Hey you two stop ignoring me damn it " Serafall said after recovering from Isamu's bold words.
" I mean I did tell you I am quite eccentric. "
" Hello I am still here " Serafall said. Right now she even forgot why she was angry due to being ignored. This just came to show her childlike personality.
Sona looked at Isamu with a deadpan expression making Isamu slightly smirk at her.
" I mean , she clearly has test . It is quite rare to see someone who watches Magical Girl Milky Spiral Seven She is clearly cultured unlike you " Isamu said.
" Wait you have watched Magical Girl Milky Spiral Seven ? " Serafall asked as her droopy expression was replaced with stars.
" Of course. It have repeated it like six times when I was a kid. "Isamu said.
Serafall jumped at the boy surprising the two. She hugged him as her breasts found their way to his head. Sona had to seperate the two .
" From now on you are My new BFF. We can watch the whole series again with you " She proudly declared.
" Sure but how about we skip the fortune arc , that part was boring " Isamu said.
" Couldn't agree more , The author really was lazy with that one " Serafall agreed.
" My future husband and sister are brain-dead " Sona murmured.
" That's mean So-tan " Serafall said with a teary face .
Isamu patted her in the back .
" There there , She is just uncultured , we will eventually teach her our ways " Isamu said.
" But So-Tan is so mean and doesn't want me near her " Serafall said clearly sad.
" Tch Don't make me the bad one here " She was ignored.
" How about you marry me , that way you can have a cultured husband and So-tan to yourself " Isamu suggested but Sona delivered punch to his gut.
" Stop picking girls left and right you bastard " Sona said .
" But you're my number one you know that " Isamu said.
" Bullshit "
" Want me to prove it to you ? " Isamu asked as he stole a kiss to her cheeks .
Sona blushed.
" Just don't get ahead of yourself. " Sona said.
" Never darling " Isamu said.
" Oh I want a kiss too " Serafall said and Isamu did so to her cheek.
They however were unaware of a man watching them from afar , Sirzechs.
He was beyond furious. First this half fallen angel dare to hurt his god by stealing his women , now he dares to compromise his sister ? And just when he wanted to deal with him using Serafall , the man was able to make seduce her .
' How should I kill you ? Perhaps I can send assassins to kill you in your sleep. ' Sirzechs involuntary shuddered at the thought . He felt a bad preomonition would happen if he did that .
